Segregation evaluation of concrete pavements under excessive vibration using electrical resistivity measurement

Autor: Jin Soo Bang, Hong Jae Yim

Publikováno v: Case Studies in Construction Materials, Vol 19, Iss , Pp e02300- (2023)

Concrete pavements are typically constructed using slipform pavers. A vibration process is required to consolidate low workability concrete. However, improper vibration of fresh concrete can cause concrete pavement degradation, such as aggregate segr

Introducing a New Quantitative Evaluation Method for Segregation of Normal Concrete

Autor: Dongyeop Han, In-Deok Han

Publikováno v: International Journal of Concrete Structures and Materials, Vol 15, Iss 1, Pp 1-15 (2021)

The aim of this research is to provide a quantitative method for evaluating concrete segregation. Because of various conditions of concrete materials, mix proportions, and delivery, concrete can be segregated. The acquisition inspection executed in c

Segregation is the unintentional separation of the fresh components of concrete or mortar, which can have negative impacts on the mechanical, transport and durability properties of the cured product. The problem is acute in self-consolidating concret

Lightweight aggregate concretes (LWAC) are versatile and interesting materials for projects that require greater structural efficiency. Due to the difference that exists between the densities of the materials used in these types of concrete, during t
